Quarter 2 Energy

Energy and Waves

TermDefinition
Energy the ability to do work or change
Potential Energy stored energy
Kinetic Energy energy in motion
Radiant Energy Light energy stored in particles called photons that move as a wave.
Sound Energy energy produced by the vibration of an object. It moves as a wave.
Chemical Energy energy stored in molecules that can be released by a chemical reaction. It is stored in food, gasoline, and other fossil fuels.
Electrical Energy energy stored in the electrons of atoms and released when the electrons move.
Thermal Energy heat energy stored in an object, as the object's temperature, that can be released as heat.
Nuclear Energy energy stored in the atoms of all things, released by a nuclear reaction (splitting atoms in fusion or fission).
Mechanical Energy kinetic energy of objects in motion or the potential energy stored in an object (gravitational energy).
Wave energy that travels from one location to another.
Wavelength the distance between 2 crests, or 2 high points on a wave.
Wave speed the distance travelled through motion per unit of time.
Frequency how often the waves occur or the number of times a crest or trough passes through a given point in a certain time.
Amplitude the intensity of the wave or the height of the wave, measured from the center of the wave to its highest point (crest) or the lowest point (trough).
Mechanical wave waves that MUST travel through a medium (solid, liquid, gas).
Electromagnetic wave waves that DO NOT need a medium (solid, liquid, gas) to travel. These waves can travel in space.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
